Triple Lobe Rotary Blowers
Elmo Rietschle manufactures a number of triple lobe rotary blowers with volume flow capacities from 22 to 8,580 m3/hr. This range includes dry running positive displacement vacuum pumps (the R-WVB series) and compressors (the R-WPB series). As dry running machines there is no need for oil or grease in the compression chamber. Only the gear box and bearings are oil lubricated and they are separated from the pumping chamber. Two non contacting triple lobe rotors rotate against each other in the compression room. The triple lobe rotors avoid pulsation problems while conveying air or gas mixtures.
Robust and economical, these dry running modular design triple lobe rotary blowers are factory customised to meet the varying demands of each customer’s application. They come as either basic or compact units and with or without frequency control. There is also an option to have an acoustic enclosure on the compact units.
The Elmo Rietschle range of rotary lobe blowers can be found in a number of industries and applications including environmental engineering where they are used for; central vacuum systems, domestic wastewater systems, drying, filter rinsing, gas stirring, sludge oxygenation, tank aeration and much more.
